RESUMO
Objectives: Ginkgo biloba leaf extract (GBLE) and L-carnitine extract are a commercial product used as a nutraceutic herbal widely. They have antioxidant and reactive oxygen species (ROS) scavenger. This study hypothesized that GB and L-carnitine may have protective effects against pentylenetetrazol (PTZ) induced oxidative damage in kidney in male albino rats. Materials and Methods: A total of 80 male albino rats were equally divided into eight groups (G1, control; G2, GBLE; G3, L-carnitine; G4, Pentylenetetrazole; G5&G6, pre and post treated PTZ with L-carnitine groups respectively; G7&G8, pre and post treated PTZ with GBLE respectively). Results: Serum urea, creatinine, uric acid and cystatin c were significantly increased in PTZ group when compared with control. Also; kidney homogenate MDA and DNA fragmentation were increased when compared with control while, significant decrease in CAT, SOD, GST and TAC in PTZ when compared with control. On other hand pre and post-treatment with L-carnitine and GBLE improved these parameters. Conclusions: The results revealed that; the treatment with L-carnitine improved these parameters more than GBLE and the results of post treatment were better than pre-treatment.
RESUMO
68 strains of PS. aeruginosa, 23 strains from fish, 15 strains from poultry and 30 from human were isolated on cetrimide King's "A" medium, cetrimide nutrient agar and Pseudomonas CN supplement SR 102. Culture characteristics of the isolates on the three media as well as biochemical reactions were discussed. Pathogenicity tests of PS aerugionsa strains to mice and rabbits revealed that the virulence caries according to the source of the strain as well as the dose used in infection
